AI Technical Summary

Technical Problem

Existing waterproof neck devices are not effective at protecting neck radiotherapy patients from water during showering. Water can easily leak through the gaps between the waterproof laryngeal mask and the patient's skin, affecting treatment outcomes and increasing the risk of infection.

Method used

A waterproof device comprising a protective membrane, an elastic absorbent layer, and an adhesive layer was designed. The protective membrane is wrapped around the neck to form a sealed area through the adhesive layer, the elastic absorbent layer absorbs leaked water, and the combination of tightening components and ear loops improves stability and ensures waterproof effect.

Benefits of technology

It provides effective protection for the neck, prevents water from seeping into the neck, reduces the risk of infection, and improves the safety and comfort of the bathing process.

Abstract

This utility model belongs to the field of medical assistive devices and discloses a waterproof device for assisting patients undergoing neck radiotherapy to bathe, including a protective film. The protective film is made of elastic material and is stretched to wrap around the patient's neck. A first adhesive layer and a second adhesive layer are provided on the side of the protective film that is close to the patient's skin. The first adhesive layer is arranged along the lower edge of the protective film and is used to adhere to the patient's skin. The second adhesive layer is arranged along the edge of either side of the protective film and extends from the lower end of the protective film to the upper end of the protective film, and is used to adhere to the other side of the protective film. An elastic absorbent layer is fixed near the upper part of the side of the protective film that is close to the patient's skin. By forming a ring-shaped area around the neck with the protective film, effective protection of the patient's neck is achieved. At the same time, when a small amount of water leaks downwards between the upper end of the protective film and the patient's skin, the leaked water can be absorbed by the elastic absorbent layer to prevent a small amount of water from leaking into the neck.
